Effect of Organic and Inorganic Fertilizers on Yield and Yield Components of Common Bean (Phaseolus vulgaris L.) in Badakhshan, Afghanistan

Abstract

For a high and usable yield of common bean, key challenges include the high expense of inorganic fertilizers and their excessive usage. Concurrently, integrated crop management methods are worldwide needs for agriculture and the environment. Because of this, the present study was carried out at the Research Farm of the Agriculture faculty at Badakhshan University in Afghanistan in order to evaluate the effect of single and combination applications of NPK, chicken manure, and the combine of NPK and chicken manure (NPK + Ch. M) with different concentrations on the growth, yield, and yield components of common bean during the summer season (June to September) of the year 2022. A randomized complete block design (R.C.B.D) was used for the experiment, and there were three replicates of each factor. It was discovered that NPK (15:15:15) at 150 kg per ha produced the highest plant in terms of height (54 cm), number of leaves per plant (63), and branch count per plant (7). These findings were based on the data that were obtained. Also, it was discovered that the optimum performance of common bean with regard to 25gr pod number/plant (PNP) ha-1 and 253g pod weight/plant was achieved with the combination of NPK (15:15:15) at a rate of 150 kg/ha and chicken manure at a rate of 20t/ha above control. This was shown to be superior to the performance of the control. A substantial (p 0.01) influence on grain production was found to be caused by the application of NPK + Ch. M. On the other hand, the NPK fertilizer and a combination of NPK and Ch. M fertilizer had a substantial impact on the grain production. The integrated of NPK + Ch. M fertilizer ha-1 treatment produced the highest grain yield (4.97t/ha-1), followed by Ch. M produced (4.22t/ha-1) seed yield. The control treatment, in which no organic or inorganic fertilizer was applied, produced the lowest grain yield (2.83t/ha-1), making this significantly higher than the control treatment. According to the findings of this study, an integrated application of NPK plus Ch. M is an effective way to get Phosphorus as well as other key elements that are necessary for the development and production of common bean.
